To all whom it may concern;-

Be it known that l, Gnmntns T. BLOOMER, acitizen of the United States, residing at Newark, in-the county of Wayne and State of ew York, have invented a new and useful Egg-Box, of which the following is a specification.

The present invention appertains to paper boxes or receptacles, and aims to provide a paper blank of novel formation, and adapted 2 It is theobject of the invention to provide a paper box blank of such formation, as to reduce to a minimum the amount of stock required, and toalso reduceto a minimum the amountof waste. The blanks are of such peculiar configuration that they in-- terlock or interfit in a unique manner, so that the blanks may be cut readily from the continuous sheet or roll of stock. It is, however, also the object of the 'invention to to provide a blank which when folded ,to provide a box, will produce a thoroughly practical and efficient box, and one whichis even desirable and advantageous over pre-'-' vaillng boxes ofthe same general character.

5 Since the blanks are interfitted ina unique manner, a large quantity of blanks-may be cut from the sheet of stock, wherebythe number of blanks which canbe' cut from a given length of stock will be the maximum,

t without jeopardizingthe' elficiencyof the boxes when the blanks are folded.

With the foregoing and other objects in view which will appear as the description proceeds, the invention'resides -in the com- .45 bination and arrangement of" parts'and' in the details of' construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be niadewithin the scope of what is claimed, without departing'fi-om' thespirit of the invention.

The invention is illustrated in'the accompanying' drawings, wherein v Figured is a plan view of several of the present blanks, illustrating how they interlock or interflt, so that they can be cut from acontinuous sheet or roll of stock. Fig. 2 is a perspective view of an egg box foldedfrom one of the blanks. Fig. 3 is a perigective view of the box partially folded. 'g. 4 is a plan view of the box in folded position. Fig. 5 is an end view of the box. The'formationof the blank will first be described, and the various'portions will be designated, for convenience, by the names of the portions of the box which they subsequently form. The edges of certain portions of the blank and other parts are also described as if t e blank were folded to formthe box. -Theblank, which may be constructed of paper or other suitable stock, comprises a rectangular bottom 1 having front and back Walls 2 and 3 at its opposite edges, respectively, and end walls 4: at its ends. The back wall '3' has a rectangular top or cover 5,

andthe 'fron't'wall 2 has flaps 6 at its ends,

while the back wall 3 'is provided with flaps Tat its ends. The top 5 has a flap 8 at its free'edge, and'a flap 9 at each end. The ends of the flap 8- are provided with short tabs 10 which are'adapted to be secured to -th'e'adjacent ends of the flaps 9.

The-various portions of the blank have peculiar characteristics, whereby the desired objects are carried out. Thus, the flaps 9 and dwalls tare slightly narrower than tlfe front 'iand back walls, to thereby reduce thespace' between the successive blanks, as illustratcdin Fig. 1. The flap 8 is also narrower than" the front and back walls to decrease thewidth of the sheet or strip from which the blanks are cut. The flaps 8 and 9 of thetop 5 may be narrower than the walls of the body of the box since they slip into the body and fully serve to close the space between the top and walls of the body. The flaps 6 and 7 of the front and back walls are tapered and have their upper edges flush with the upper edges of the front and back walls, whereby." when the blank is fold- I ed,( the upper edgeportions of the flaps 6 and 7 will project above the end walls 4 to increase the height of the end walls to that of the front and back walls. The lower edges of the flaps 6 and 7 are inclined or cut obliquely, as at 11 and 12, respectively, whereby the said edges of the flaps 6 and 7 converge toward the upper edges of said flaps. The free ends of the flaps 6 and 7 are blunt whereby the free ends of the flaps 6 and 7 are arranged to abut against one another, when the blank is folded, for closing the gaps between the respective flaps 6 and 7. The flaps 6 and 7 are relatively long, or are longer than the widths of the end walls 4 and flaps 9, but notwithstanding this fact, the blanks are arranged to interlock or interfit with the edges of the end walls and flaps 9, abutting, as seen in Fig. 1.

In order that the box may be folded, the front wall 2 is provided with diagonal scores or fold lines 13 extending upwardly from its lower corners, and the end walls 4 are provided with diagonal scores or fold lines 14 extending upwardly from their lower rear corners. The flaps 9 of the top 5 are provided with diagonal or oblique scores or fold lines 15 extending from the free corners of the top 5.

The upper rear corner portions 16 of the end walls 4 are adapted to be'secured by means of an adhesive or by any other suitable means to the flaps 7 and the said corner portions 16 are provided with notches or recesses 17 for receiving the free ends of the flaps 7 of the adjacent .blanks as seen in Fig. 1.. This allows the flaps 7 to project beyond the end walls 4 and flaps 9.

In forming the box from the-blank, the walls 2, 3 and 4 are folded upwardly, and the flaps 6 are properly secured to the end walls 4, while the corner portions 16 of the end walls 4 are properly secured to the flaps 7. The tabs 10 of the flap 8 are suitably secured to the adjacent ends of the flaps 9. When the box is thus completed the flaps 6 and 7 project above the end walls 4 and abut against one another to finish the ends of the body properly and-without the presence of objectionable gaps or openings 1n the ends of the body, although in certain cases, if desired, the flaps 6 and 7 may be cut shorter, which would leave gaps or openings between said flaps. Ordinarily, this would not be necessary or desirable. The free portions 18 of the flaps 7 project beyond the fold lines 14, whereby when the body is erected, the portions 18 in overlapping and resting against the end Walls 4 beyond the fold lines 14, will serve to brace the ends of the body and limit the outward movement thereof. When the box is filled, such as by a filler and eggs disposed in the cells thereof, the top or cover 5 may be readily closed, by slipping the flaps 9 and 8 thereof within the body of the box. When the box is empty, or before it is filled, it may be compactly folded into a fiat condition. Thus, the front wall 2 may be folded upon the bottom 1, the end walls 4 and flaps 6 folding upon the bottom 1 and front wall 2, and the back wall 3 folding upon the end walls 4 while the flaps 7 and corner portions 16 of the end walls 4 fold between the back wall 3 and the body portions of the end walls 4. The flaps 9 of the top 5 may be folded against the top to enable the flap 8 to be folded against the top and flaps 9. The boxes may therefore be completed at the factory and be shipped in a compact condition, to be readily unfolded or erected by the user.

Particular attention is directed to the manner in which the blanks interfit, as illustrated in Fig. 1, whereby a minimum amount of stock is necessary with a minimum amount of waste, and furthermore the blanks may be cut from a continuous sheet or strip of stock. Notwithstanding these facts, the blanks when folded to complete the boxes, will provide boxes of desirable and effective construction. The adjacent blanks are reversed, as seen in Fig. 1, and the adjacent edges of the blanks will thus interfit in the manner illustrated. Due to the difierences in the widths of the flaps 8 and front walls 2 of the blanks, the bottoms 1 and tops 5 will be offset slightly relative to one another, but even then, each blank will interfit at its opposite edges with the reversely disposed adjacent blanks of like formation. The flaps 9 and end walls 4 of each blank abut against the end walls 4 and flaps 9 of the adjacent blanks, respectively and the lower or oblique edges of the flaps 7 will abut against one another, while the notches or recesses 17 accommodate the free ends of the said flaps 7. The flaps 8 and 9 may fit upon the outer side of the body, as well as on the inside thereof, as will be obvious.

Having thus described the invention, what is claimed as new is A blank box comprising a rectangular bottom having front and back walls at its edges and end walls at its ends, the back wall having a rectangular top, the free edge of the top having a flap, the ends of the top each I having a flap, the said front and back walls each having a flap at each end, the first mentioned flap having short tabs at its ends to be secured to the adjacent ends of the second mentioned flaps, the first and second mentioned flaps and end walls being slightly narrower than the front and back walls, the flaps of the front and back walls being tapered and having their uppcredges flush with the upper edges of the front and back walls, the flaps of the front and back walls being longer than the widths of the end Walls and seconei meliitioneet flaps and the my own, ][-have hereto afixedl my signature upper rear corners of the end walls haj fving in the presence of two Witnesses. notches whereby the opposite edges 0 the blank ai'e adapted to interfit with like blanks CHARLES O 5 in reversed position, as and for the purposes Witnesses:
